Ok, I have an important question regarding custom boot logos for the Untethered Jailbreak. So far the only way I'm able to get them to work at all is with the PNG's packaged with QuickFreedom 1.1.0, and those appear to be transparent but with little black pixels all around the transparent spots. So far all of my logos (which worked perfectly fine on my tethered jailbreak before) with a solid background color or any other solid color absolutely refuse to work whatsoever. I have also tried Exosion's FirmwareBundle and I get the exact same results. My question is, what exactly do I need to do to a PNG to get it to be recognised properly for an Untethered Jailbreak? What software, what settings should I use when saving, 8-bit, 24-bit, 32-bit, and exactly how do I make the PNG's transparent properly?
